Niigata Prefectural Sports Park, Sports and recreational park in Chūō-ku, Niigata, Japan.

Niigata Prefectural Sports Park is the southeastern athletic section of Toyano Lagoon Park in Chūō-ku, Niigata. Its north area holds Denka Big Swan Stadium, a sub-ground, a canal, a landscape pond and a nature study garden; the south area has the prefectural baseball stadium and a skate park. A road bridge crosses the grounds, linking the two sides.

The sports complex was established in November 1998, marking a turning point for athletic development in Niigata Prefecture. A major baseball stadium was added later to expand the facilities and accommodate larger events.

The park serves as a meeting place where local sports clubs and community members gather regularly to train and compete together. People from the area use the facilities as part of their daily sports routines and come together for organized events.

The S7 Sports Park Line runs from Niigata Station's bus terminal to the Sports Park in about 20 minutes. The last bus back to the station leaves early, around 18:24 on Sundays and holidays. On match days, shuttle buses run from the station to the park's bus terminal, and parking becomes paid and must be booked in advance.

The park's canal and landscape pond sit beside the Denka Big Swan Stadium, and the northern area holds a nature study garden. The stadium's sub-ground, Denka Swan Field, was completed after the main stadium. The park began as the venue of the 1998 national urban greening fair, Niigata Midori Monogatari '98.
